+  The 64<sup>th</sup> release of NuttX, Version 5.17, was made on January 19, 2010 and is available for download from the
   <a href="http://sourceforge.net/project/showfiles.php?group_id=189573">SourceForge</a> website.
   The change log associated with the release is available <a href="#currentrelease">here</a>.
   Unreleased changes after this release are available in CVS.
   These unreleased changes are listed <a href="#pendingchanges">here</a>.
 </p>
 <p>
-  This release includes initial support for USB host in NuttX.
-  The USB host infrstruture is new to NuttX.
-  This initial USB host release is probably only beta quality;
-  it is expected the some bugs remain in the logic and that the functionality requires extension.
-</p>
+  This release follows close on the heels of the 5.16 release and extends the USB host capabilities first introduced in that version.
 <p>
-  Below is a summary of the NuttX USB host implementation as extracted from the
-  <a href="NuttxPortingGuide.html">NuttX Porting Guide</a>:
-</p>
 <ul>
-  <h3>6.3.9 USB Host-Side Drivers</h3>
-
-  <ul>
-    <li>
-      <p>
-        <b><code>include/nuttx/usb/usbhost.h</code></b>.
-        All structures and APIs needed to work with USB host-side drivers are provided in this header file.
-      </p>
-    </li>
-    <li>
-      <p>
-        <b><code>struct usbhost_driver_s</code></b>.
-        Each USB host controller driver must implement an instance of <code>struct usbhost_driver_s</code>.
-        This structure is defined in <code>include/nuttx/usb/usbhost.h</code>.
-      </p>
-      <p>
-        <b>Examples</b>:
-        <code>arch/arm/src/lpc17xx/lpc17_usbhost.c</code>.
-      </p>
-    </li>
-    <li>
-      <p>
-        <b><code>struct usbhost_class_s</code></b>.
-        Each USB host class driver must implement an instance of <code>struct usbhost_class_s</code>.
-        This structure is also defined in <code>include/nuttx/usb/usbhost.h</code>.
-      </p>
-      <p>
-        <b>Examples</b>:
-        <code>drivers/usbhost/usbhost_storage.c</code>
-      </p>
-    </li>
-    <li>
-      <p>
-        <b>USB Host Class Driver Registry</b>.
-        The NuttX USB host infrastructure includes a <i>registry</i>.
-        During its initialization, each USB host class driver must call the interface, <code>usbhost_registerclass()</code>
-        in order add its interface to the registery.
-        Later, when a USB device is connected, the USB host controller will look up the USB host class driver that is needed to support the connected device in this registry.
-      </p>
-      <p>
-        <b>Examples</b>:
-        <code>drivers/usbhost/usbhost_registry.c</code>, <code>drivers/usbhost/usbhost_registerclass.c</code>, and <code>drivers/usbhost/usbhost_findclass.c</code>,
-      </p>
-    </li>
-    <li>
-      <p>
-        <b>Detection and Enumeration of Connected Devices</b>.
-        Each USB host device controller supports two methods that are used to detect and enumeration newly connected devices
-        (and also detect disconnected devices):
-      </p>
-      <p>
-        <ul>
-          <li>
-            <p>
-              <code>int (*wait)(FAR struct usbhost_driver_s *drvr, bool connected);</code>
-            </p>
-            <p>
-              Wait for a device to be connected or disconnected.
-            </p>
-          </li>
-          <li>
-            <p>
-              <code>int (*enumerate)(FAR struct usbhost_driver_s *drvr);</code>
-            </p>
-            <p>
-              Enumerate the connected device.
-              As part of this enumeration process, the driver will
-              (1) get the device's configuration descriptor,
-              (2) extract the class ID info from the configuration descriptor,
-              (3) call <code>usbhost_findclass(</code>) to find the class that supports this device,
-              (4) call the <code>create()</code> method on the <code>struct usbhost_registry_s interface</code> to get a class instance, and
-              finally (5) call the <code>connect()</code> method of the <code>struct usbhost_class_s</code> interface.
-              After that, the class is in charge of the sequence of operations.
-            </p>
-        </ul>
-      </p>
-    </li>
-    <li>
-      <p>
-        <b>Binding USB Host-Side Drivers</b>.
-        USB host-side controller drivers are not normally directly accessed by user code,
-        but are usually bound to another, higher level USB host class driver.
-        The class driver exports the standard NuttX device interface so that the connected USB device can be accessed just as with other, similar, on-board devices.
-        For example, the USB host mass storage class driver (<code>drivers/usbhost/usbhost_storage.c</code>) will register a standard, NuttX block driver interface (like <code>/dev/sda</code>)
-        that can be used to mount a file system just as with any other other block driver instance.
-        In general, the binding sequence is:
-      </p>
-      <p>
-        <ol>
-          <li>
-            <p>
-              Each USB host class driver includes an intialization entry point that is called from the
-              application at initialization time.
-              This driver calls <code>usbhost_registerclass()</code> during this initialization in order to makes itself available in the event the the device that it supports is connected.
-            </p>
-            <p>
-              <b>Examples</b>:
-              The function <code>usbhost_storageinit()</code> in the file <code>drivers/usbhost/usbhost_storage.c</code>
-            </p>
-          </li>
-          <li>
-            <p>
-              Each application must include a <i>waiter</i> thread thread that (1) calls the USB host controller driver's <code>wait()</code> to detect the connection of a device, and then
-              (2) call the USB host controller driver's <code>enumerate</code> method to bind the registered USB host class driver to the USB host controller driver.
-            </p>
-            <p>
-              <b>Examples</b>:
-              The function <code>nsh_waiter()</code> in the file <code>configs/nucleus2g/src/up_nsh.c</code> and
-              the function <code>nsh_waiter()</code> in the file <code>configs/olimex-lpc1766stk/src/up_nsh.c</code>.
-            </p>
-          </li>
-          <li>
-            <p>
-              As part of its operation during the binding operation, the USB host class driver will register an instances of a standard NuttX driver under the <code>/dev</code> directory.
-              To repeat the above example, the USB host mass storage class driver (<code>drivers/usbhost/usbhost_storage.c</code>) will register a standard, NuttX block driver interface (like <code>/dev/sda</code>)
-              that can be used to mount a file system just as with any other other block driver instance. 
-            </p>
-            <p>
-              <b>Examples</b>:
-              See the call to <code>register_blockdriver()</code> in the function <code>usbhost_initvolume()</code> in the file <code>drivers/usbhost/usbhost_storage.c</code>.
-            </p>
-          </li>
-        </ol>
-      </p>
-    </li>
-  </ul>
+  <li>
+    The LPC17xx USB host controller driver was extended to (1) add support for low-speed devices,
+    (2) handle multiple concurrent transfers on different endpoints (still only one TD per endpoint), and
+    (3) handle periodic interrupt endpoint types.
+  </li>
+  <li>
+    Add a USB host HID keyboard class driver.
+    Now you can connect a standard USB keyboard to NuttX and receive keyboard input for an application.
+  </li>
 </ul>
+<p>
+  And other changes as detailed in the ChangeLog.
